How to Install a SIM Card into an X2 Data Logger

While it is always recommended that a SIM card be sent to NexSens for installation prior to shipment, in some cases it may be necessary for a user to install a SIM card themselves. The following article steps through this process.

Caution!!!- Be sure to statically ground yourself prior to touching any of the electronics inside the X2 logger

 

Tools Required:

-Small Flathead Screwdriver

-Phillips Head Screwdriver

-3/16″ Hex Driver or Adjustable Wrench

Instructions

  1. Locate the green plastic wire from its track in the base of the X2’s aluminum housing.
  2. Slide tweezers or the tip of the screwdriver packaged with the X2 beneath the wire to expose it.
  3. Pull the end of the wire while applying pressure to the top of the X2 to remove it from the track. Tweezers or needle-nose pliers can be used if needed. 
  4. Pull up on the enclosure to separate it from the X2 base.
  5. Press down on the tabs of the top-facing UW8 P0 and UW6 Direct JST connectors and gently pull to remove them from the PCB.
  6. Proceed removing the downward-facing UW8 P1, UW8 P2, and UW6 RTU JST connectors  from the PCB in a like-manner.
  7. Remove the 4 visible Phillips-head screws and lock washers from the top of the Main Board
  8. Gently lift up on the Main Board to disconnect the board-to-board connector and expose the RTU board.
  9. Use a 3/16″ nut driver or adjustable wrench to remove the four standoffs on the bottom of the PCB.
  10. Tip the RTU board to reveal the modem and SIM card slot.
  11. Gently push the tray downwards to unlock it as indicated by the inscribed ‘open’ arrow on the tray.
  12. Swing the tray lid open .
  13. Place the SIM in the tray such that the indentation on the card will align with the same indentation on the holder when closed. 
  14. Gently swing the tray closed and press upward gently to lock it back into place.
  15. Place the RTU board back on top of the base and hand tighten the four standoffs back in place.
    1. Follow up with an 1/8 of a turn using the nut driver or adjustable wrench.
  16. Align the board-to-board connector and place the main board back on top of the RTU board, pressing down gently until the connectors lock into place.
  17. Tighten the top PCB back in place using the four Phillips screws and lock washers.
  18. Re-connect the downward-facing JST connectors to the proper ports as inscribed on the PCB, gently pressing in until a click is heard.
    1. UW8 P1 (connects directly below the UW8 P0 port)
    2. UW8 P2 (aligns with the SD card slot)
    3. UW6 RTU (connects directly below the UW6 Direct port)
  19. Re-connect the upward-facing JST connectors
    1. UW8 P0
    2. UW6 Direct
  20. Slide the enclosure back over top the X2 base, ensuring that no wires are pinched.
  21. Align the wire entry with the machined body tag on the aluminum base.
  22. Push down on the top of the enclosure and feed the wire back into its track.
  23. Connect the antenna and power up the X2, monitoring the blue LED blinking pattern above the X2 symbol at the top of the logger for up to 60 seconds to verify a successful cellular connection is established as outlined in the Quick Start Guide.
    1. A repeated pattern of three consecutive blinks indicates the X2’s attempt at cell connection was successful.
    2. A single repeated blink indicates the X2 is retrying the cellular connection
